San Mateo County: Motorcyclist dies in head-on collision

A motorcyclist was killed in a head-on crash around 1:45 p.m. Thursday on a winding stretch of Skyline Boulevard in unincorporated San Mateo County, according to the California Highway Patrol.

CHP Officer Amelia Jack said the crash occurred about three-quarters of a mile south of Page Mill Road when the motorcyclist -- described only as a man in his 30s -- swerved across the center divide of the two-lane road and into the path of a northbound Acura sedan.

"The rider was ejected and succumbed to his injuries at the scene," Jack said.

She said it does not appear that drugs or alcohol were involved in the collision, and investigators were looking into whether excessive speed played a factor.

The driver of the Acura was not injured.

Both lanes were closed following the accident, prompting a traffic advisory that lasted until the road was reopened around 4:15 p.m.

Any witnesses to the accident are asked to contact Officer Wester at 650-369-6261.
